Zob Inline Diffused Straight Tube with UFO Flat Disc Percolator This beast from Zob Glass is not for the weak-lunged smoker. It's approx. 18 inches tall. This beauty features an inline diffuser and a UFO flat disc percolator. By the time the smoke makes it's way through the inline diffuser and the UFO percolator, and gets to your lungs it's smooth as silk! This tube is made for serious rips! It has a splash guard and a three-prong ice pinch. This pipe is made of 5mm. thick American made glass, and sits on a 5 inch glass base. This pipe comes with the Zob standard 14mm. ground glass slide. Zob goes to great lengths to make sure each piece is one of a kind, so the label will most likely be different than the one pictured. - Perc: Inline Diffuser and UFO Flat Disc Percolator - Features a Splash Guard and Three Prong Ice Pinch - Height: 18.00 inches - Base Width: 5.00 inches - Glass Thickness: 5.00mm. - Tube Diameter: 50.00mm. - Inline Diffuser Length: 8.00 inches - Slide: 14.00mm.
